Broken Arrow Police said a QuikTrip was evacuated Monday morning in the 2400 block of East Kenosha Street when a woman suffering an emotional disturbance barricaded herself inside the store.
Police said they got a call from a relative around 9 a.m. about a woman who hadn't shown up for work at a nearby business. The relative was concerned about the woman, and a gun was missing from the family's residence.
The woman called the relative and said she was inside the restroom in the QuikTrip. Police negotiated with her for about an hour inside the store.
The standoff ended when the 35-year-old woman fatally shot herself.
No one else was injured in the incident. Broken Arrow Police said there will be counseling available for the officers who responded to the suicidal woman.
Mike Thornbrugh, spokesperson for QuikTrip, said: "Absolutely a very sad tragedy. Our thoughts and prayers go out to the family."
